(Note: These are sometimes called "silver" or "lead" cents by people who aren't aware they're really steel.)Lincoln cents (1944-46, 1961-mid 1982) : brass (95% copper, 5% zinc)Actually, modern pennies(post 1982) are 97.5% Zinc with the remaining 2.5% being electrolytically plated copper. Up till 1982, pennies were made from and alloy composed of 95% Copper, 2-3% Zinc and 2-3% Tin.Additionally, the 1943 "wartime penny" or the "steel penny" was made of steel with zinc plating, so that copper could be saved for military use. A few of these pennies were accidentally minted early in 1943 with bronze blanks left over from 1942, and are prized by collectors.
Are pennies made out of zinc?
Because you asked this in the US currency section, I guess you are really talking about the one cent piece. This is sometimes called a penny because it is roughly the same size, shape, and colour as a one new penny. This used to be made of pure copper, but is now made of copper-plated zinc, so if you file away the coating, you will see the zinc inside.
What was the purpose of the steel coating on a 1943 penny?

What would cause the density of pennies to vary?
Cents have been made of different metals over the last 150 years, so they'd have both different weights and densities. 1864 - mid-1982 except for 1943 : 95% copper / 5% tin and zinc. 1943 : steel with a thin coating of zinc mid-1982 - present : zinc with a thin coating of copper
